Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

The interference of the screen of the mobile terminal on the radio frequency receiving performance mainly comes from the MIPI (Mobile Industry Processor Interface, mobile industry processor interface) bus interface of the DSI (Display Serial Interface, display serial bus interface), which can also be called MIPI interface, MIPI The interface is widely used in mobile terminals, providing an interface standard with lower power consumption and higher transmission efficiency. According to the different transmission requirements of the MIPI interface, its clock frequency needs to meet different requirements. For example, when used for a liquid crystal display (LCD for short), the MIPI clock frequency must be greater than a certain frequency in order to meet the LCD refresh rate requirement. In actual use, the mobile terminal may need to be compatible with several MIPI-interface screens. If the MIPI-interface screen sends signals at a higher frequency, it will interfere with radio frequency reception performance.

Usually, the interference of the MIPI interface mainly comes from the following two types:

(1) The MIPI clock is divided by 4:

MIPI data is transmitted in units of 1 byte, each byte stores a sub-pixel, and the data between sub-pixels is similar, so when the data is transmitted in units of bytes, there will be periodic repetitions, which will result in a 4-frequency division of the MIPI clock interference.

(2) MIPI clock divided by 12:

When MIPI data is transmitted in 4-lane, a RGB (R(red), G(green), B(blue), RGB color mode) data combination will be formed on each pair of differential lines. Due to the gradual change between general image frames, there is similarity between the above RGB data combinations, and then the 3byte data is transmitted periodically and repeatedly, which corresponds to the 12-frequency interference of the MIPI clock.

The above-mentioned interference of the MIPI interface can easily affect the communication function of the mobile terminal, and even affect the normal communication of the user, resulting in a low user experience. Based on this, embodiments of the present invention provide a method and device for selecting a MIPI frequency point, and a mobile terminal, so as to alleviate the influence of the clock frequency of the MIPI interface on the communication function of the mobile terminal.

To facilitate the understanding of this embodiment, a method for selecting a MIPI frequency point disclosed in the embodiment of the present invention is firstly introduced in detail.

A flow chart of a method for selecting a MIPI frequency point as shown in Figure 1, the method can be applied to a mobile terminal, comprising the following steps:

Step S102, acquiring the current location of the mobile terminal;

In order to reduce the power consumption of the mobile terminal during operation, the mobile terminal can periodically obtain the current location of the mobile terminal during operation, or obtain the current location of the mobile terminal when the mobile terminal meets certain preset conditions. location. Wherein, the preset condition may include one of the following: power on and restart, detection of a SIM card hot-swapping event, and a change in the location of the mobile terminal;

During specific implementation, the region where the mobile terminal is currently located can be determined according to the PLMN (Public Land Mobile Network, public land mobile network) or MCC (Mobile Country Code, MCC, mobile country code) of the current serving cell of the mobile terminal.

Step S104, determining the preferred MIPI frequency point set corresponding to the above region according to the interference relationship table.

The interference relationship table is pre-stored on the mobile terminal.

Step S106, setting the current MIPI frequency point of the mobile terminal as a MIPI frequency point in the preferred MIPI frequency point set.

The method of this embodiment obtains the region where the mobile terminal is currently located, and determines the preferred MIPI frequency point set corresponding to the region according to the interference relationship table, and then sets the current MIPI frequency point of the mobile terminal as a MIPI in the preferred MIPI frequency point set The frequency point reduces the interference of the MIPI frequency point on the radio frequency receiving performance, effectively guarantees the communication quality of the mobile terminal, and improves the user experience of using the mobile terminal.

In order to make the interference of the MIPI frequency point on the radio frequency reception performance as small as possible, the above method also includes: obtaining the frequency point information of the current network environment of the mobile terminal; optimizing the above-mentioned preferred MIPI frequency point set according to the frequency point information of the network environment; The optimized set of preferred MIPI frequency points adjusts the MIPI frequency point of the mobile terminal. Based on this, the present embodiment also provides a flow chart of another MIPI frequency selection method shown in FIG. 2 , which can be applied to a mobile terminal and includes the following steps:

Step S202, if the mobile terminal satisfies the preset condition, obtain a set of preferred MIPI frequency points corresponding to the region where the mobile terminal is currently located;

The preset condition is the same as that described above, and will not be repeated here.

In actual use, the available frequency bands of mobile terminals deployed in different regions are different, and the frequencies that can be set by the MIPI interface of mobile terminals are also different under different frequency bands. Therefore, in the process of selecting MIPI frequency points, it is necessary to determine the mobile The region where the terminal is currently located, and then determine the corresponding set of preferred MIPI frequency points according to the region.

In specific implementation, the available frequency bands in each region have the corresponding preferred preset MIPI frequencies on the screen. By obtaining the current region where the mobile terminal is located, the actual deployment frequency bands in the current region can be known, and then the corresponding preferred MIPI frequency points can be obtained. In order to adjust the MIPI frequency point of the mobile terminal in the current region according to the following steps S204 to S210.

Step S204, setting the current MIPI frequency point of the mobile terminal as a MIPI frequency point in the preferred MIPI frequency point set;

Step S206, acquiring the frequency point information of the current network environment of the mobile terminal;

This step S206 may be performed periodically during the use of the mobile terminal, or after each network registration of the mobile terminal is completed. The above-mentioned frequency point information of the network environment may include the current working mode, frequency band and neighboring cell information of the mobile terminal.

Step S208, optimize the preferred MIPI frequency point set according to the frequency point information of the network environment;

Step S210, adjusting the MIPI frequency point of the mobile terminal based on the optimized set of preferred MIPI frequency points.

The above method in the embodiment of the present invention can set the current MIPI frequency point of the mobile terminal as a frequency point in the preferred MIPI frequency point set, optimize the preferred MIPI frequency point set according to the frequency point information of the network environment, and based on the optimized preferred MIPI frequency point set MIPI frequency point set adjusts the MIPI frequency point of the mobile terminal to realize the selection of the optimal MIPI frequency point for setting under the current network state, reducing the interference of the MIPI frequency point on the radio frequency receiving performance, and effectively ensuring the communication quality of the mobile terminal , thereby improving the experience of the user in using the mobile terminal.

Usually, the location of the mobile terminal can be determined by the PLMN or MCC of the current serving cell. When the current location of the mobile terminal is determined, the corresponding table between the PLMN or MCC and the available frequency bands of the mobile terminal can be searched to obtain the information in the current location. The actual deployed frequency band, and then determine the preferred MIPI frequency point set corresponding to the current region.

Specifically, the above step of obtaining the preferred MIPI frequency point set corresponding to the region where the mobile terminal is currently located includes: (1) determining the region where the mobile terminal is located according to the PLMN or MCC of the current serving cell of the mobile terminal; The preferred MIPI frequency point set.

Taking MCC as an example for illustration, usually, the MCC is a mobile country code composed of 3 digits, which uniquely identifies the country to which a mobile user belongs. Table 1 shows a correspondence table between an MCC and an actual deployed frequency band. For convenience, Note that Table 1 only shows the situation of two groups of MCCs. For details, reference may be made to relevant documents to know the correspondence between MCCs and actually deployed frequency bands, which is not limited in this embodiment of the present invention.

Table 1:

It can be seen from Table 1 that the actual deployment frequency bands in different regions are different, therefore, when selecting MIPI frequency points, the preferred MIPI frequency point sets are also different.

Taking MIPI frequency = 523MHz as an example, the multiplier frequencies corresponding to the 4-divided frequency and the 12-divided frequency, and the multiplied frequencies of different levels are projected into the frequency band of the mobile phone's working frequency point to form corresponding interference.

Generally, an interference relationship table between frequency bands supported by the mobile terminal and MIPI frequency points can be stored in a designated memory (such as a non-volatile memory) of the mobile terminal. The interference relationship table represents different MIPI frequency points and the frequency points supported by the mobile terminal. The interference intensity relationship of each operating frequency point in each frequency band. Therefore, the process of searching for a preferred MIPI frequency point set locally can be performed through the interference relationship table. Based on this, the embodiment of the present invention provides a flow chart of another MIPI frequency point selection method, as shown in FIG. 3 , including The following steps:

Step S302, if the mobile terminal satisfies the preset condition, determine the region where the mobile terminal is located;

Wherein, the process of determining the region where the mobile terminal is located may be determined according to the PLMN or MCC of the current serving cell of the mobile terminal.

Step S304, searching the frequency band corresponding to the above-mentioned region in the interference relationship table stored locally;

Wherein, the interference relationship table stores interference parameters between preset frequency points in each frequency band and MIPI frequency points supported by the mobile terminal;

Usually, the interference relationship table can be obtained during the early development process of the mobile terminal and stored in the non-volatile memory of the mobile terminal to represent the interference intensity between different MIPI frequency points and each operating frequency point of each frequency band supported by the mobile terminal relation.

Step S306, according to the interference parameter of the MIPI frequency point corresponding to the found frequency band, select the MIPI frequency point from the interference relationship table;

Considering that there are many frequency bands supported by the mobile terminal, the above-mentioned process of selecting MIPI frequency points includes: according to the interference parameters of the MIPI frequency points corresponding to the found frequency bands, count each MIPI frequency point supported by the mobile terminal against the found The total number of frequency bands without interference in each frequency band; select the MIPI frequency point according to the total number of frequency bands, for example, select the MIPI frequency point whose total number of frequency bands is greater than the set threshold, or sort the MIPI frequency points from large to small according to the total number of frequency bands, and select the sorting MIPI frequency points of the previous set number in the following MIPI frequency points.

Step S308, forming the selected MIPI frequency points into a preferred MIPI frequency point set;

After the mobile terminal acquires the above-mentioned preferred MIPI frequency point set, the current MIPI frequency point can be set as a MIPI frequency point in the preferred MIPI frequency point set, and the specific setting steps are shown in steps S310 to S312.

Step S310, determine the average interference value of the MIPI frequency points in the preferred MIPI frequency point set according to the interference parameters in the interference relationship table;

Wherein, the above-mentioned interference parameters may include whether the MIPI frequency points in the preferred MIPI frequency point set interfere with the frequency band supported by the mobile terminal, the frequency values of interference at all levels (such as frequency division by 4, frequency division by 12, etc.), and interference intensity .

Step S312, setting the MIPI frequency point corresponding to the minimum average interference value as the current MIPI frequency point of the mobile terminal;

The execution process of step S314 to step S318 is consistent with that of step S206 to step S210 shown in FIG. 2 , and will not be repeated here.

In order to facilitate the understanding of the above MIPI frequency point selection method, Table 2 shows an interference relationship table, as shown in Table 2:

Among them, frequency band A (specifically A1, A2...A6, etc.) to frequency band E are the frequency bands supported in the region where the mobile terminal is currently located, and frequency point X, frequency point Y, etc. are MIPI frequency points in the preferred MIPI frequency point set, Each frequency point corresponds to an interference parameter, wherein the frequency point in the interference parameter is each working frequency point included in the MIPI frequency point.

After the mobile terminal determines the location according to the PLMN or MCC of the current serving cell, it can look up the actually deployed frequency bands and MIPI frequency points included in the region according to the interference relationship table shown in Table 2.

Table 2:

Taking Table 2 as an example, the preferred MIPI frequency point set can be determined according to Table 2, for example, frequency point X and frequency point Y can be included. After determining the preferred MIPI frequency point set, the average interference value of the MIPI frequency point in the preferred MIPI frequency point set can be determined according to the interference parameters in the interference relationship table shown in Table 2, and then the preferred MIPI frequency point is determined, wherein, preferably The MIPI frequency point can also be called the first-level preferred MIPI frequency point, and the rules for determining the preferred MIPI frequency point can include: (1) first select the MIPI frequency point setting with less interference; Both frequency band C and frequency band D have interference, and frequency point Y has interference to frequency band A and frequency band E. At this time, frequency point Y is the MIPI frequency point with less interference; (2) If there are two MIPI frequency points interfere with the number of frequency bands If they are the same, the frequency point with the weakest interference in the frequency band is preferred. The frequency point with the weakest interference refers to the MIPI frequency point with the smallest average interference of each frequency point of the relevant frequency, which can be calculated by the interference intensity in Table 2, that is, the MIPI frequency point corresponding to the minimum average interference value is selected. (3) setting the current MIPI frequency point of the mobile terminal as the preferred MIPI frequency point.

After the mobile terminal successfully registers on the network using the preferred MIPI frequency point, the preferred MIPI frequency point set can be further optimized according to the frequency point information of the network environment, so that the mobile terminal can adjust the mobile terminal's frequency based on the optimized MIPI frequency point set. MIPI frequency point.

Figure 4 shows another MIPI frequency point selection method, which is implemented on the MIPI frequency point selection method shown in Figure 3, and further describes the optimization of the preferred MIPI frequency point set according to the frequency point information of the network environment The process, as shown in Figure 4, includes the following steps:

Wherein, the execution process of step S402 to step S414 is consistent with that of step S302 to step S314 shown in FIG. 3 , and will not be repeated here.

Step S416, acquiring the current working mode of the mobile terminal;

Usually, the mobile terminal can perform network registration, or the mobile terminal can obtain the current working mode after checking the current network status update, such as single card operation mode, dual card operation mode, and GSM (Global System for Mobile Communication, Global System for Mobile Communication) Mode, CDMA (Code Division Multiple Access, Code Division Multiple Access) mode and LTE ((Long Term Evolution, Long Term Evolution) mode, etc.

Step S418, judge whether the working mode supports VoLTE service, if yes, execute step S420; if not, execute step S424;

Among them, the VoLTE (Voice over LTE) service is a voice solution based on IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) network to achieve service control through LTE network access as a service, which can realize data and voice services under the same network Unite.

If the VoLTE service is supported, the LTE frequency band should be optimized first, because mobile terminals supporting the VoLTE service generally use the LTE frequency band to complete main services such as voice, information, and data.

Therefore, if the VoLTE service is supported, step S420 is performed.

Step S420, obtaining the LTE frequency band used by the VoLTE service, the LTE frequency band includes: the frequency band used in the carrier aggregation process;

Among them, the LTE frequency band is multi-carrier joint work, including carrier aggregation and dual card VoLTE and other modes.

Step S422, optimize the preferred MIPI frequency point set according to the LTE frequency band and the frequency point corresponding to the LTE frequency band;

Wherein, the optimization process is performed based on the principle of minimum interference of the MIPI frequency point to the frequency point corresponding to the LTE frequency band. Specifically, it can be calculated according to the interference relationship table shown in Table 2, and the frequency points corresponding to the LTE frequency band and the LTE frequency band, select the MIPI frequency point that does not interfere with the current LTE frequency band, and establish on the basis of the aforementioned preferred MIPI frequency point set Second-level preferred MIPI frequency point set.

If the frequency in the second-level preferred MIPI frequency point set is unique at this time, use the current second-level preferred MIPI frequency point set to adjust the MIPI frequency point of the mobile terminal.

If the frequency in the second-level preferred MIPI frequency point set is not unique at this moment, then obtain the current mobile terminal in GERAN (GSM EDGE Radio Access Network, wireless access network) or UMTS (Universal MobileTelecommunications System, universal mobile communication system) mode Working frequency bands and frequency points, on the basis of the above-mentioned second-level preferred MIPI frequency point set, select MIPI frequency points that do not interfere with the current working frequency band in GERAN or UMTS mode according to the interference relationship table shown in Table 2 to form a third-level optimization A collection of MIPI frequency points.

If the frequency in the third-level preferred MIPI frequency point set is unique at this time, use the current third-level preferred MIPI frequency point set to adjust the MIPI frequency point of the mobile terminal.

If there are multiple MIPI frequency points in the optimized third-level preferred MIPI frequency point set at this time, then continue to obtain the adjacent cell frequency band of the mobile terminal; The set of points is optimized; wherein, the optimization process is also based on the principle of minimum interference between the MIPI frequency point and the frequency point corresponding to the adjacent cell frequency band.

If the frequencies in the above-mentioned three-level preferred MIPI frequency point sets interfere with adjacent cell frequency bands, select the MIPI frequency point with the weakest interference intensity. Wherein, the MIPI frequency point with the weakest interference intensity refers to the MIPI frequency point with the smallest average interference value suffered by the frequency points of all adjacent cell frequency bands; if the preferred MIPI frequency point is not unique, the default selection is the first Frequency;

When the judgment result of the above step S418 is negative, it means that the current mobile terminal does not support the VoLTE service, and then step S424 is executed.

Step S424, obtaining the working frequency band of the mobile terminal in GERAN or UMTS mode;

Step S426, optimizing the current preferred MIPI frequency point set according to the working frequency band and the frequency point corresponding to the working frequency band;

Wherein, the optimization process is performed based on the principle of minimum interference of the frequency point corresponding to the working frequency band of the MIPI frequency point at this time.

Specifically, MIPI frequency points that do not interfere with the current working frequency band can be selected based on the above-mentioned working frequency band in GERAN or UMTS mode, and the interference relationship table shown in Table 2, so as to complete the optimization of the preferred MIPI frequency point set.

If the optimized MIPI frequency point set contains only one MIPI frequency point at this time, step S428 is executed, and the MIPI frequency point at this time is the finally obtained optimal MIPI frequency point.

If the MIPI frequencies included in the optimized preferred MIPI frequency point set are not unique, MIPI frequency points that do not interfere with the current LTE frequency band can be selected according to the current LTE frequency band and the interference relationship table shown in Table 2 to form a three-level preferred MIPI collection of frequencies. At this point, reference may be made to the processing procedure for the three-level preferred MIPI frequency point set in step S422.

Step S428, adjusting the MIPI frequency point of the mobile terminal based on the optimized set of preferred MIPI frequency points.

Specifically, the adjustment process may include: setting the MIPI frequency point in the optimized preferred MIPI frequency point set to the driver of the mobile terminal screen, and completing the selection process of the MIPI frequency point after the setting is completed.

The MIPI frequency point selection method provided by the embodiment of the present invention can dynamically adjust the MIPI frequency point on the screen in real time according to the current network state of the mobile terminal, and then select the optimal MIPI frequency point for setting under the current network state, effectively reducing the In addition, the process of optimizing the optimal MIPI frequency point set according to the frequency point information of the network environment is also helpful to meet the multi-mode and multi-frequency working scenarios of global roaming terminals. The production cost of the terminal, while reducing the interference of the MIPI frequency point on the radio frequency reception performance, effectively ensures the communication quality of the mobile terminal, thereby improving the user experience of using the mobile terminal.
